I've been reading that AdMob banners don't show in preview mode. That's OK, but I need to know how much space to leave on the layout to take the banners into account.
Am I right in thinking the banners for portrait mode appear at the bottom of the screen?
Also, as I'm building for a 4k screen in portrait mode (viewport size 2160 x 3840) and the banner sizes for smart portrait are Screen width x 32/50/90, I'm guessing the largest banner size will be used - in this case 2160(screen size) x 90 - meaning there will be black bars either side of the banner, correct?
So the largest area I have to factor in for banners will be 2160 x 90?
